Clunk When Starting or Stopping - 2008 F-250CCSB4x4

[jascott]

I have an 08 F-250 CC SB 4x4 Diesel truck that has since new clunked when starting out from a stop and/or coming to a stop. I have 16k on it now and am getting really tired of dealing with it...

The clunk starting is when I let off the brake and just apply the throttle. It feels like something slips and then clunk.

The clunk when stopping is the same as starting, except when coming to a stop.

This is unloaded or when loaded w/ cargo and/or trailers.

Any help? I know I can go to the dealer, but I don't want to un-spartan my truck for this...

Thanks in advance!

I have test driven several '08s and the one I own now does this as well. Sounds just like a broken U-joint or something. I suppose it's just gearlash - but believe it or not I came here to this website today for this VERY purpose. Hopefully get some resolution to it.
Gearlash in the transfercase? transmission? I assume it's normal, but just don't know entirely...

Here you go, just a couple threads down from this one....
